Supertex inc. HV7360 High Speed, 100V 2.5A, Two or Three Level Ultrasound Pulser Features General Description HVCMOS technology for high performance The Supertex HV7360 is a high voltage, high-speed, pulse generator with built-in, fast return to zero damping FETs. This High density integration AC coupled pulser high voltage and high-speed integrated circuit is designed for 0 to 100V output voltage portable medical ultrasound image devices, but can also can 2.5A source and sink minimum pulse current be used for NDT and test equipment applications. Up to 35MHz operating frequency 2.0ns matched delay times The HV7360 consists of a controller logic interface circuit, 2.5, 3.3 or 5.0V CMOS logic interface level translators, AC coupled MOSFET gate drivers and high Low power consumption and very simple to use voltage and high current P-channel and N-channel MOSFETs as the output stage. Application The peak output currents of each channel are guaranteed Medical ultrasound imaging to be over 2.5A with up to 100V of pulse swing. The AC Piezoelectric transducer drivers coupling topology for the gate drivers not only saves two NDT ultrasound transmission floating voltage supplies, it also makes the PCB layout easier.
